Description

  The present invention relates to a novel switch electrode, a planar electrode plate for a switch electrode, and a mat switch.

  A mat switch in which a long switch or the like is arranged on a mat body is used in a house or a building for the purpose of crime prevention to detect intrusion of a suspicious person at night or the like.

A conventional example of such a mat switch will be outlined below.
A conventional mat switch 51 shown in FIG. 13 has a flat plate shape and an insulator 52 having a protrusion 53 protruding upward at a predetermined interval, a flat plate shape disposed on the insulator 52, and the above-described mat switch 51. A lower electrode plate 55 made of a conductive metal material provided with an opening 54 through which the projection 53 passes at a position corresponding to the projection 53, and a lower surface of the lower electrode plate 55 abuts on the upper surface of the projection 53. And an upper electrode plate 56 made of a conductive metal material arranged at a small distance from the lower electrode plate 55, and a jacket 57 made of an insulating material covering the outer periphery including the lower and upper surfaces thereof. .

  In the mat switch 51, when a suspicious person or the like is placed on the upper surface of the mat switch 51 and an external force F acts on the mat switch 51 without the projection 53, the upper electrode plate 56 bends downward and comes into contact with the lower electrode plate 55 to be turned on. Thus, a detection signal indicating the presence of a suspicious person or the like is obtained.

  However, in the case of the mat switch 51, since the structure includes the lower electrode plate 55 and the upper electrode plate 56 made of a conductive metal material, it is expensive in terms of cost to make the overall shape other than the rectangular shape, and it is transported. There is a restriction that it cannot be rolled or folded for convenience of storage.

  Further, it is necessary to provide a protrusion 53 for supporting the upper electrode plate 56 on the insulator 52 and an opening 54 in the lower electrode plate 55, and the manufacturing process becomes complicated.

  A conventional mat switch 61 shown in FIG. 14 has a plurality of long switches 63 built in a flat parallel mat body 62 made of an elastic insulating material, and a suspicious person or the like is placed on the top of the long switch 63 so that an external force F is applied. A detection signal indicating the presence of a suspicious person or the like is obtained by utilizing the fact that the long switch 63 is turned on when it acts.

  In the case of this mat switch 61, a crossover wiring between a plurality of long switches 63 is necessary, and it takes time to manufacture, and the area between the individual long switches 63 and the long switches 63 is inevitably insensitive. It is not always sufficient in terms of detectability of suspicious persons.

  The conventional mat switch 71 shown in FIG. 15 and FIG. 16 has a conductor fixed to a flat knitted wire or a flexible thin film on both upper and lower surfaces of a flat insulator 72 made of a flexible insulating material and provided with an opening 73. The flexible electrode plates 74 and 75 are attached, and the outer periphery thereof is covered with a jacket 76 made of a flexible insulating material.

  As shown in FIG. 16, the mat switch 71 is configured such that when a stepping pressure by a person or the like, that is, an external force F is applied from above the opening 73, the electrode plate 74 bends downward via the outer cover 76 and the electrode plate 75. Touch and turn on. As a result, a detection signal indicating the presence of a person or the like can be obtained.

  In the case of this conventional mat switch 71, although it is possible to wind from the structure described above, the shape restoring property of the electrode plate 74 is not sufficient, it is easy to malfunction, and when the external force F acts on the flat insulator 72. An opening 73 for contacting the electrode plates 74 and 75 is indispensable, and a region where the opening 73 does not exist is inevitably a non-sensing portion, which is not necessarily sufficient in terms of detectability of a suspicious person or the like.

  In Patent Document 1, a lower electrode using two electrode wires is arranged on the lower side, and an upper electrode using an energization line facing the lower electrode is arranged on the upper side to form a switch unit. There has been proposed a mat switch in which a plurality of parts are arranged at intervals by insulating parts.

However, even in the case of the mat switch of Patent Document 1, the region where the insulating portion exists becomes a non-sensing portion.
